Human Ebola Vaccine Trials Begin, a Newly Discovered Dinosaur from Zimbabwe, and Wildfires in Europe Are Producing "Fire Clouds"

First, human vaccine trials for the rare Bundibugyo Ebola virus have started in the Democratic Republic of the Congo. The outbreak, which began in May 2026, has resulted in more than 3,200 reported cases. The newly discovered sauropodomorph dinosaur from Zimbabwe, named Musango matusadonaensis, lived around 210 million years ago during the Late Triassic period.

This find suggests that southern Africa had unique dinosaur populations during that time. In Bulgaria, industrial poultry farming has contributed to the evolution of a major foodborne pathogen called Campylobacter jejuni. Meanwhile, woolly mammoth bones have emerged from the Danube Riverbank in Bulgaria due to drought conditions.

Finally, wildfires in Europe are generating dangerous "fire clouds" that can trigger lightning, fierce winds, and new fires, further complicating firefighting efforts.
